Emmanuel Agyeman Badu will miss the 2012 African nations cup as a result of a suspected broken leg sustained in Thursday's Europa League
Badu was stretchered off in the 29 minute as Udinese reached the last 32 of the Europa League after a hard-fought 1-1 draw with Celtic.
Gary Hooper earned the visitors the lead on the half-hour but the prolific Antonio Di Natale levelled just before the break.
